.To all whom it may concern:

Be it known that I, Nenn C. INHITNEY, a citizen of the 5United States, residing at Terre Haute,k in the county of VigoI and State of Indiana, have invented certain new and useful Improvements in Automatic Tile-Cutters; and I hereby declare that the following is a full, clear? and exact descrip tion'thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is a novel improvement in mechanism for cutting drain tile and other plastic continuous products after the same have been ejected from the molding mechanism. 'Ihe object of the invention is to provide a machine which can be used in connection with a machine for expressing tile or like plastic productsin a continuous form and for cutting the tile into equal lengths after it is ejected from the machine and while it is being moved from said forming machine to point of discharge. Another object of the invention is to make a machine wherein the tile may be severed accurately and cleanly into desired lengths and upended and discharged onto a conveyer, the operations of cutting and discharging taking place during the continuous movement of the tile from the forming machine to the receiving conveyer.

The invention includes novel mechanism for supporting the plastic material during the cutting operation and then up-ending same and transferring it onto a delivery belt; also novel mechanism for cutting the tile while it is traveling; also other minor novel features of construction and operation and novel combinations of parts which will be hereinafter set forth.

In the accompanying drawings I have illustrated a machine particularly designed and adapted for cutting plastic pipe into desired tile lengths or sections as one embodiment of the invention; and I will eX- plain the invention with reference to said machine to enable others to adapty and use the same, but I do not consider the invent tion restricted to the particular mechanism shown and described, and refer to the claims for summaries of the essentials of the invention and novel features of construction and novel combinations of parts for which protection is desired.

In said drawings:

Fig. l() is a top plan view of Fig. 9.

Fig 1l is a detail view of one of the trough sections.

The machine illustrated in the drawings comprises two endless carrier chains operating side by side in a horizontal plane.' the inner ends of these carriers being adjacent n l but spaced apart. 'Ihfese carriers are formed of a series of links A as hereinafter explained which are pivotally connected to.- gether like a chain and are guided around the front and rear guide wheels Z1A and Z3 and front and rear guide wheels Z2 and Z4' as indicated in Fig. Yl. l

rlChe guide wheels Z1, Z2, Z3, Z4, have peripheral flanges Z6 on their upper ends (see Fig. 9,) which flanges serve as eontinuations of the overhead guide L for the rollers D, as the links pass around the guide wheels. These guide wheels are journaledpon vertical stub shafts suitably secured in the supporting framework of the machine.l which framework may be of any suitable desired construction. As shown each'carrier is made up of twenty links A making 2 0 right and 20 left. As shown in 5 each lini-cvhastwo depending lugs A1, which are attached to axles B carrying on their inner ends wheels C and on their outer ends rollersV D. The wheels C l engage guide tracks suitably mounted on the frame, the straight way portion'ofwhich tracks are preferably formed of .channel iron C1y while the outer ends of the trackwhich are concentric with the carrier'pulleys or vwheels may be iiat as shown at C1". The wheels C support the links A and the rollers D are passed under overhead guide plates D1 which counteract the weight of the parts of the tile supportingmembers attached toV the plates as hereinafter described, the guide D1 being suitably-support ed on the frame So as to connect the upper sides of the wheels D, (see Fig. 8). Mounted on the outer ends of the axle B and to confine the rollers D thereto are curved strips P which are adapted to engage and fit against thev face of the sheave wheels or pulleys Z1, Z3, Z2, Z4, as the carrier links pass around the wheels and thus keep the links properly spaced as they pass around the said wheels. Each link is provided on its upper face with boxes or studsfi2 in which is journaled one end of a Ll-shaped rod E, (Figs. Ll,

5, and 8) and to the body of this rod is idly attached the bottom member H1 of one of the trough sections, Vand to this bottom member is hingedlyV attached the side me iiber H of such trough section; the side member may be adj ustedrelat-ively tothe bottom member of the Vtrough section by any suitable means. As shown a notched bracing lcverf 'HG' (Figs.v 2 and 8) is pivoted to the other arm of the rod E andits upperen'd rests Vagainst the outer side ofthe trough member H and maybe held in adjusted position against thistrough member iymeens of a bale lll pivoted to thermeniber l-l and engagn ing a notch in the bracing leve ln this way the body member H of the trough section can be held in lany desired position.

The trough `sections are right and left am it takes two such sections to support a. tile but each' of the sections are constructed and operated alike on both the right and'left hand carriers but at the inner runs of theV carrier the right hand section on the cross ksection of one carrier coacts with the left hand section on the crosssection of the other carrier and together make a complete support and holder for the tile Vas hereinafter explained. Y

in horizontal position but they are operated 'lhe trough sections normally lie at the propertimes and manner by suitable means. Y Y

As ,shown a lever F is pinned tothe shaft E betweenthe lugsie? and this lever is bentV as shown in'Figs. 5 Vand 7 and its angular portion depends beside the Vlink adjacent'the g wheels C and beside the guide track C1. @ne

end this lever is adapted to'engage e can'ls attached to the frame at a point beyond where-the cuttiiig'joff the'tile is com* :Then the lever F'passes the'cam FS and thel trough sections return to normally horizontal position as they rpass around the forward sheaves. Y

The ,positions they traverse cam FS are indicatedin Fig. 6.

Each link A. carries a. tile cutter which is preferably composed of a bow L provided with a cutting wire LVW.' rihe bow Lt'is-attached to or rormed integral with a shaft or 'rod L3 which is journaled iii studs on the upper side of each link (see Figs. l, 5, 8) with the shaft L? lying at right angles to the bow L4 and on the innerendof this shaft is attached a lever L2 which lies `at right angles ofthe trough sections yas posed between a collar L5 on shaft 3 and the forward lug A3 on thelink and one end of the spring is connected to the collar and the other end to the link vand thespring lbeing wound so thatit will tend to normally "turn the `shaft L3. and hold the bow raised andthe leve-r L2 inV lowered position, Vas showni'n Fig. Y Y V Y l The spring N normally tendsto slide the shaft L? longitudinally of the lugs A3 but such Vmovement of the shaft by the spring is limited by mea-ns of a collar Lion the shaft La.' rlhis shaft L3 is moved longitudinally atthe proper ltime so asto compress the spring N by means of a cani lever M, which is pivoted on the side of the link A and has its upper end adapted to engage the'end of the/shaft L3. (See Figsjt' and 5). TheV lower end of the lev r M at the proper time engages with a camlil1 as hereinafter eX-Y At the proper time the roller L1 on the V end of lever L? engages a cam plate L11.

(Seelfigs. l, 8, 9 and'l) V.This cam plate extends beside the'innerruns of each haltl Y section oftheearrier beginning at a point slightlyY in advance lof where the cutter should begin its operation and continuing to a ,point slightly beyond that at Vwhich the bow hasj completed its operationV and has com'- pletely retracted, and between these points the roller L1 is so shiitedthat as the link carryin the bow traverses lengthwise'of thiscam plate iso the cutter is lowered farther and farther so as to cause the wire L1* to accurately sever the pipe line on the trough sections into tile lengths and then the bow is retracted by means of a secondary cam plate L1? `which is arranged above and conforms to the curvature of the primary or forward cam plate L11. These Vcam plates may be supported by suitable brackets L16, L17, L18, L1 and L20 as indicated in Figs. 9 and 10.

Extendingy lengthwise of the machine and between thel adjacent inner runs of the carriers is an endless belt I which passes over wheels T3 and T13 mounted respectively on `shafts T13 and T3s suitably attached to the trame (see Fig. 4The upper run of the belt I may be supported by pulleys or roll ers J which are' suitably mounted in side frames of the machine so as not to interfere with the levers F. -Attached to the belt I at proper intervals along its length are lugs l which are adapted', to engage with the forward ends of the links A on each carrier, when on the inner runs of the carrier, and cause the carriers to move with the.

belt I. The forward motion of the belt I4 causes the carriers to move around the sheave wheels. In the example shown there would be 7 carrier links A simultaneously in contact with lugs K on each side of the belt. This arrangement insures that the car- .riers will move accurately and the speed be controlled by the speed of the belt I for purpose hereinafter explained.

The carrier I is adapted to be driven by any suitable means. Preferably on the shaft T33 is a pulley T23 driven by a belt S from a pulley T ona drive shaft T40 which latter may be driven by any suitable means and the tension of this belt S is regulatable by a tension roller T1 which may be of any suit-` able construction and adjusted in any well known manner so as to regulater the tension ofthe belt. From. belt I the tile could be passed over a belt Rto a belt Q. The belt It may have supporting` rollers R1 arranged beneath its upper run andthe belt Q, could have supportingrollers Q1 arranged beneath its upper run. The belt R is driven in the proper direction and may be passed over` pulley T1l1 on a shaft T15 which shaft carries a pulley T25 4driven by a belt T16 from a pulley T5 on the shaft T17 carrying the pulley T4, over which the receiving end of the carrier Q runs. This transfer belt It and carrier belt Q. may be of any suitable construction and are only diagrammatically illustrated in the drawings.

` In the machine shown there are 20 links each carrying a half trough section asdescribed and the trough sections on the right and left carriers coincide at the adjacent runs of the carriers and travel in the direction of the belt I and the adjacent right half sections and left half sectionslon the Adown the center of the machine with and over belt I.

Operation.

The machine for forming or molding the pipe is not shown but may be of any well knownkind and should be located. at the receiving end of the belt I which is the left hand side of the machine shown in Fig. l so that the pipe or other object exuding continuously from the forming machine-would be received upon and supported by the trough sections, the parts thereof enter between the wheels Z1, Z2, the point at which the uncut pipe or material is delivered onto the cutting machine being indicated at the point B in Fig. 1.

A. continuous lengthof uncut tile is fed from the forming machine to the cutting machine at the point marked B, Fig. l and is received by the trough sections and carried therein down the center of the machine. For reasons which will be explained later, uncut tile travels in the trough the length of four sections before the cutting is completed.

After the cutting wire has completed its downward motion, through the column, the trough section immediately ahead of the cut, tilts upward, hinging from the front and while the cutting bow and wire returns to normal the trough section keeps tilting upwardly until it is in a vertical position and the tile it has carried is stood onend upon the conveyer belt I, which runs the full length of' the machine directly underneath the trough. When the tile is placed on end as described, the trough sections separate, the right half section returning around sheave wheel Z4 and the left-half section returning around sheave wheel Z3. The tile however travels straight kforward onr the belt. Whether the cut happens to be from a I left bow or a right, the point where the cut is completed is exactly the same.

In traveling down the center of the machine the cam4 roller L1 on each cutting` lever L2 comes in contact with the cam L11 and rises upward and inward with the lever L2, causing the bow L4 to move downward over the column of pipe and the wire L14 severs a tile or section from j the column,

completing the cut at a designated'gp'oint slightly'beyond the center of theV machine.

Thereafter as vthe sections travel thetilting levers F F right and left comeinto-contact with ytheir canisfFfv and the trough section, ahead of the cirtgjust made, is tilted upwardly from the rear (as it is hinged at the front). As shown as the end of thelpreced cams F8 FS (right and left) until they are standingT in a vertical position with lthe tile it has carried placed Von endon'the belt I. Vllhe tilting cams FS then permitV the two opposite half troughV sections to lower Vas they part and pass around the opposite sheave wheels Z3, Z4 aiid'by tlie'time the the machine.

half sections have completed the turn around Ytheir sheavel wheels,V to 'the outboard sides on the machine, they have returned to their normal' Vhorizontal Vposition andi-are ready to again receive and support the un!A ciittile column as they meet after turning around sheave wheels Z1 and Z2 at of the 'machine' and above belt l.

Ars Stated before the tileA travels Ythe length of 'four trough sections before it is severed. The traction between the tile columnV and the -four above mentioned trough sections, tendsV to govern the speed of the cutting table and holdit to the saine speed that` the column of cla-y flowsffrom the forming machineacross the table. VThis is made 'possible by Vproperly adjustingY the tensioning roller T1 on belt 1S which drives The traction Vof Y troughsections holds the beltl to proper speed, the idler belt S slipping Von the pulleys should the speed of the tile column be slower than that at which thepulley T would otherwise drive the belt I. rilhus the greater partv of thedeadweight of thecperating parts of the machine'is driven by a source of power separatefrom .the tile column,v which tile column does just enough work to. govern the speed'of the machine. `The drive conveyer belt I only extends a -foot or'two beyond the delivering end of the machine, and there the cut tile are'transferred automatically to conveyerbeltQ as described. This keeps the load Aconstant on the :belt I, while theload 'on belt Qiiuctuates due to its being unloaded at different points'at dilferent times Vbut this iiuctuation ofrload docsnot interfere with the centery .rincones adapted Y for cutting other `forms f off-plastic vmaterial into "desired lengths.: and r Iv `con- Sider.; all such: adaptationsof the invention within the scope of. the'invention and claims.

lFurther l' do notconsider the invention restricted to the specific construction of the carrier, 'or ofthe cutting mechanism. or of the trough sections and the operating devices sliown in the drawings as variousmod- A ifications and changes may be made in these elemental features while retaining the essentials of the invention; and all such changes and modifications within the :scope of theinvention are intended to be covered in the broader claims wherein features of construction are not specificallydesignated.
